PACKLESS RADIATOR-VALVE.

Specification of Letters Patent.

Patented Jan. 21, 1908.

Application filed July 24. 1906 Serial No. 327.583.

To all whom it may concern:

Be it known that I, J OHN (Jonas, a citizen the United States, residing at Des Moines, in the county of Polk and State of Iowa, have invented a certain new and useful Packless Radiator-Valve,' of which the following is a specification.

The object of my invention is to provide a valve for radiators in which the movementof the valve on its seat as required to open and close the passage-way through the valve chamber is in a rotary direction and the pressure of the heating medium upon the valve in a direction tend' to raise it from its seat is counterbalanced I a pressure disk so ar- I ranged as to hold t e valve to its seat with a pressure in excess of the pressure applied to the valv: in a direction tending to raise it from its seat, so that when there is a light pressure of the heat' medium the valve will be held to its sent i 251 a light pressure, and when there is a heavy pressure of the heating medium, the counterbalancing pressure dis will exert astrong pressure in a direction holding the valve to its seat.

A further object is to provide a valve of this kind of simple durable and inexpensive construction in which all of the parts are i readilv accessible so that they may be rcl place or repaired easily and quickly.

My invention consists in the construction. arrangement, and combination of the various parts of the valve, whereby the objects con- 5 templated are attained, as hereinafter more fully set forth, pointed out in my claims and f illustrated in the accompanying drawings, in which Figure 1 shows a vertical, central, sectional view of a packlcss radiator valve emljmdying 1 my invention. Fi 2 shows a top or plan view of same with ile valve cover, the valve chamber and valve removed. Fig. 3 shows i an inverted plan view of the valve chamber 3 and valve. F' 4 shows a detail, pcrspective view of the va vc detached from the valve casin and valve chamber, and Fig. 5 shows av side 9 ovation of a radiator with my in'iproved valve applied thereto as in practical use.

Referring to tlu fllfCUlllPiUtVlllg drawings. f I have used the reference numeral H! to indicate the body portion of thc valvc casing. This bodyportion is substantially cylindrical in shape and is provided at its top with a circular screw threaded flange I]. The interior of the valve is open, and at one end is an inlet opening 12 for a heating medium to i jectcd below the inlet opening 25 having a smooth central may be which a nipple 13 may be screwed, which nipple may e connected with an elbow 14 to receive a supply pipe 15. Between the inlet opening 12 and the circular flange 11 is a disk-shaped flat partition 16 having two segmental openings 17 and 18 therein on opposite sides of its center. The top .of this partition 16 is round smooth to receive the valve holder, lereinafter described. Surrounding the opening 18 is a partition 19 forming an outlet passage-way 20 communicating onl with the said opening 18, and secured to t e passage-way 20 is a union 21 so that the valve may be connected with a radiator in the usual wav. By means of this partition 19 the interior of the valve ass is so arren ed that the inlet ipe 12 communicates with the interior of t e valve casing and with the opening 17 while the outlet pipe cuxmnunicates only with the opening 18, and not with the interior of the valve casing be low said opening. Formed on the bottom of the valve casing is a circular flange 22 pro- 1'2 and of a diameter greater than the circular flange 11. A cup 2-3 is screwed to said flange to close its lower end, and in this cap 23 is a pet-cock 24 for drainage purposes.

Screwed to the circular flange 1 1 on top of the valve chamber is a valve cover or bonnet opening to receive the valve stem 26. This stem is revidcd at its top with :1 hand wheel 27 an: the

; stem extends through the partition 16 to a,

point near the on 23. Formed on or fixed to the upper portion of the valve stem 26 IS 3 n helm-spherical valve holder 38 having a hrond flat base face and provided ith an a-n ular socket 32 In project upwardly and to s idingly receive the guide 30. Saul parts are so arranged that the valve 31 may he nmvcd to cover either the opening 17 or the opening 18, or modc to stand in position uncovering both of said u 'icnings.

Mounted on the lower end of the valve stem 20 is a lint pressure disk 33 having a packing ring 34 in its periphery dcsigne to rest against.- the mtcrmr of the circular flange :22 and to prevent leakage of the hosting medium between the periphery of the disk and the interior of salt flange. 'lhis disk is of lar er diameter than the interior of the valve ho dcr '28.

In Fig. 5 of the drawings, 1 have shown a radiator of ordinary construction, provided with a vent pipe 36, which, in turn communicates with a return pipe 37, and this return pipe discharges into the supply i e 15 below the radiator valve. However, this arrangement of the drain and return pi es forms no partof my present invention.

n practical use and assunnn the partsof the valve to be in the position s own in Fig. 1 of the drawings, then it is obvious that a heating medium introduced throu h the supply pipe 15 will fill the interior of the valve casing and the valve holder 28. The heating medium will press equally in all directions and therefore will exert a lifting pressure upon the valve holder 28 and a downward pressure upon the valve 31. It will also exert a downward pressure upon the pressure disk 33, and as the area of this disk is greater than that of the valve holder, it will hold the edges of the valve holder firmly against the top of the partition 16 to thereby prevent leakage of the heating medium under the edges of the valve holder, and the downward pressure upon the top of the valve 31 will prevent the leakage of the heating medium through the bpening 18. By turning the valve stem a quarter revolution in either d1- plate connected with the rection, the valve is made to stand between the openings 17 and 18, and thus a free passage-way for the heating medium is provided between the inlet and outlet 0 ening. A further advantage is gained by aving the valve 31 slidinglv 30 of the valve older, because in this way the pressure of the heating medium within the valve chamber will be exerted in a down ward direction u on the valve 31, tending to hold said valve to its seat.

Having thus descri ed my invention, what I claim and desire to secure by Letters Patent of the United States, therefor is- 1. A packless valve comprising a valve chamber provided with a partition havin an opening therein, a valve holder arranger withm the casing and in contact with one side of the artition, a valve within the holder capable of covering and uncovering the opening in the partition, and a pressure valve holder and am ed within the casing on the side 0 the partition.

2.

3. n a packless valve, a valve casing provided with inlet and outlet openings, a partition within the valve casing having two openings communicating respectively with the inlet and outlet openings, a valve holder within the casing in contact with one side of the partition, a valve within the holder in one position closing one of the openings in the partition and a ressure plate connected with the valve 'hol er and disposed within the casing on the opposite side of the partition and s aced apart from the artition with one si e only exposed to the in ct openg. 4.
